SUMMARY
Magnetic flux flows through ferromagnetic materials, such as iron, due to their high permeability, which allows them to channel magnetic field lines effectively. In a toroidal configuration with a wire wrapped around it, the magnetic flux that penetrates one loop of the wire also penetrates all other loops due to the uniformity of the magnetic field within the toroid. This phenomenon is further illustrated by the behavior of a permanent magnet falling through a copper pipe, where induced currents create opposing magnetic fields that affect the magnet's motion.
